We describe the results of a comparison of reference standards between the National Institute of Standards and Technology (NIST-USA) and Physikalisch-Technische Bundesanstalt (PTB-Germany) at nominal wavelengths of 1300 nm and 1550 nm using an optical-fiber cable. Both laboratories used thermal detectors as reference standards. A novel temperature-controlled, optical-trap detector was used as a transfer standard to compare two reference standards. Measurement results showed differences of less than 1.5 × 10(-3), which is within the combined uncertainty for both laboratories.
我们描述了使用光纤电缆在1300纳米和1550纳米标称波长下，美国国家标准与技术研究院（NIST）和德国物理技术联邦研究院（PTB）之间参考标准比较的结果。两个实验室都使用热探测器作为参考标准。一种新型的温度控制光阱探测器被用作传递标准来比较两个参考标准。测量结果显示差异小于1.5×10⁻³，这在两个实验室的合成不确定度范围内。
